DIE FOR THE FORMATION OF CHAIR SEATS, BACKS, ANDTSIMILAR ARTICLES FROMCAOUTCHOUC AND OTHER PLASTIC MATERIAL.

SPECIFICATION forming part of Letters Patent No. 318,754, dated May 26,1885.

(X0 model.)

To all whom it may concern.-

Be it known that I, FREDERICK LATULIP, of Syracuse, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in Dies for the Formation of Chair Seats, Backs, andSimilar Articlesfrom Oaoutchouc and other Plastic Materials; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

This invention relates to a die or matrix for the formation of chairseats and backs and similar articles from caoutchouc, rubber, gum, andlike material; and it consists, substantially, in the die as constructedor formed, as will be hereinafter distinctly described, and pointed outin the claims.

In constructing a die in accordance with my invention I so form the sameas to produce in the finished article or product an imitation of theordinary cane seats and backs used on chairs and the like; and to effectsuch imitation I provide in the die series ofintagliated grooves orchannels, which run in longitudinal, transverse, and diagonaldirections, those which lie in longitudinal and transverse paths beingpreferably double and parallel, while those in the diagonal directionsare single and extend in two directions, crossing each other at evendistances and regular intervals apart, each set of double parallelgrooves, as well, also, as those which are diagonal thereto, allintersecting and tending to effect on the article produced series ofcorresponding ribs having the appearanceof passing over and under eachother, as though interlaced.

Between the squares on the surface'of the die formed by the intagliatedportions are formed in relief small punches or projections, which areforced through the material and produce in the finished articleregularly-arranged perforations. Also, if desired, a groove or recessmay be provided between the general surface of the die and an outer rimor flange following the main outline or contour thereof, by which isformed in the product an outer strengthening-border, by which attachmentmay be made to the structure on which it is to be employed.

For the purpose of completeness I have represented a press in which thedie is used for the formation of the articles.

Reference being had to the annexed drawings, Figure 1 represents suchpress in vertical front elevation. Fig. 2 represents a broken-ofiperspective view of the die; and Fig. 3, a top or plan view thereof,partly broken off, the two latter figures furnishing a completeunderstanding of the mode of construction.

Referring to the several parts by letter, A represents the die as awhole. a indicates the punches in relief, or projections; and Z)represents the intagliated grooves or channels, which lie inlongitudinal, transverse, and diagonal paths.

B indicates the outer rim or flange, which stands out in relief from themain body of the die, and is in the same plane as the punches b. Thegroove or recess a, formed between this flange and the general surfaceof the die, forms in the product an outer rim or border for attachmentto the chair seat or back by screws, rivets, or otherwise.

0 represents a press of the ordinary form, in which the die A is placed,the material be ing placed on a smooth surface beneath, in any suitablemanner, and the die forced down upon it from above in forming thearticle, the latter, when finished, presenting an entirely smooth undersurface, while the upper surface is given the desired configuration.

In operation the material removed by the punches is forced or squeezedoutwardly into the intagliated grooves, serving to fill them up,

and producing in the article more prominent and uniform sets of ribsthan would be prodnced by a simple impression of the die upon thematerial. This peculiarity constitutes the main feature of my invention,and it will be seen that none of the material whatever is lost orwasted, all that is displaced by the punches being equally distributedover the entire surface by the pressure brought to bear.

Having thus described my invention, what I claim is 1. A die or matrixformed with sets of 1011- gitudinal, transverse, and diagonalintagliated grooves, and projections or punches formed in relief inspaces between such grooves at uniform distances apart, substantially asdescribed.

2. A die or matrix for producing in rubber, caoutchouc, and the like,imitation of cane seats and backs for chairs and similar articles,consisting of a body having in its surface double sets of int-agliated.grooves that lie in longitudinal and transverse paths, similar singlegrooves crossing the others diagonally in two directions, and punchesformed in relief hi FREDERICK LATULIP.
